I have seen magazine articles about sounds associated with aurora, and also with meteorites. Big problem is that sound travels so slow compared to light, there would be a very large time difference. There are theories that there is energy enough in non-visible spectrum to be converted to sound by something close to the observer - aluminum foil, etc. etc. Here's a URL with discussion by a physicist.
